Adapter Sleeves are designed to mitigate gaps left between bearings and shaft diameters of dissimilar sizes. Sleeves are the most popular component for locating bearings with tapered bores onto cylindrical seats. Once mounted on the sleeve,  lock nuts are used to clamp the bearing in place. These sleeves are ideal for use on smooth shafts and stepped shafts and can be used when welding to conform different apparatuses to best fit one another.

Adapter sleeves are the most commonly used components for locating bearings with a tapered bore onto a cylindrical seat as they can be used on plain shafts or stepped shafts .Adapter Sleeves are available in various materials including steel and cast iron in a variety of measurements.

They are easy to install and require no additional location on the shaft. When used on plain shafts, the bearing can be located at any position on the shaft. When used on stepped shafts together with an L-shaped spacer ring, the bearing can be accurately positioned axially, thereby facilitating bearing mounting and dismounting.
